Whether the following statements are true or false. Also, the false statements are to be corrected: a. Arterioles reflexively dilate when blood pressure increases. b. Increased concentrations of carbon dioxide and hydrogen ions, and a decreased concentration of oxygen in the interstitial fluid cause local arteriolar constriction. c. Tissue perfusion to the heart decreases during systole and increases during diastole. d. The increase in tissue perfusion in skeletal muscles that occurs during exercise is known as hyperemia. e. The sympathetic nervous system causes vasodilation in the skin when the body temperature decreases. Introduction: Tissue perfusion is important for the survival of cells. It helps in maintaining the atrial blood pressure. It is regulated by local factors within each individual, by the process called autoregulation. It ensures that adequate amount of blood is delivered to a particular tissue for regulating their metabolic activities.
